The comedienne, who was already enduring a slew of physical ailments as well as the loss of her mother, had just been informed that she had breast cancer. But being in the business of making people laugh, Notaro had no time to be sad — so instead she transformed her sadness into jokes for the benefit of others.

Louis C.K., who raved that Notaro's set was one of "a handful of truly great, masterful standup sets" he's seen "in 27 years of doing this," has made the entire show available for download through his website at $5 a pop, with $4 from each download going to Notaro, "of which a portion will be donated to charities associated with fighting breast cancer."
